It has been proved that the interactive teaching methods are effective to involve most students and motivate them in mastering course materials.

Many educators agree that using the interactive teaching methods is not only an option but also an ethical mandatory rule for all instructors.

There are several crucial issues in applying the interactive teaching methods for engineering programs (courses):

- an instructor should ask interesting and tricky questions w.r.t to his/her course material contents

- an instructor should encourage all attempted answers or raised questions by his/her students

- an instructor should establish sufficient time room to ask questions and discuss while lecturing. A pure lecturing part should not be longer than 6 to 8 minutes without a stop for questions and short discussions

- an instructor should highlight real life examples and applications of all theoretical derivations shown via pictures, animations and videos

- and so forth.

Use of interactive teaching methods in engineering:

- In graduate programs, it is relatively easier to motivate and have most or all students in the classroom actively involved. Since the class size is smaller and graduate students are more motivated in learning.

- in undergraduate programs in particular in large class sizes, it is not as straightforward or even a challenging issue to motivate most students. Many of the undergraduate students are shy and not willing to ask questions or answer to the posed questions by their instructors.

So the question is: how to motivate and encourage the undergraduate students in engineering programs to be active learners and actively participate in-class discussions.
